MAX NOACK, OF FRIEDENAU, NEAR BERLIN, GERMANY.

METHOD OF RENDERING THE JOINTS OF THE CASE'MA'IED PORT-HOLES 0F WAR-SHIPS WATER-TIGHT.

Specification of Letters Patent.

Application filed March 8, 1909. Serial No. 482,057.

To all whom it may concern:

Be it known that I, MAX NoAoK, a subject of the King of Prussia, residing at F riedenau, near Berlin, Germany, have invented certain new and useful Improvements in Methods of Rendering the Joints of the Casemated Port- Holes of War- Ships VVater-Tight, of which the following is a specification.

This invention relates to a method and an arrangement for the packing of rifts in turret and casemate portholes.

The packings for this purpose heretofore employed have the disadvantage, that the applying and removal of the same (both from the inside as well as from the outside) is attended with a great loss of time; while the application of the packing from the outside is a menace to-human life.

It is the purpose of this present invention to obviate these drawbacks, and in order to accomplish this I provide a packing for the rifts of turret and casemate port-holes which comprises an inflatable hose shoved into the rift between the gun shield and the wall of the ship and inflated from the interior of the ship. If the packing so placed is to be removed the air or gas need only be let out of the hose and the packing can then be pulled out of the rift without any difliculty.

The packing hose employed can consist either of one single piece, which is shoved into the rift in such manner that its end's overlap, or it can also consist of two pieces, one of which can be advantageously secured for the packing of the lower part of the slit in the gun shield; while the other part can be employed for the packing of the upper and side parts of the rift, and is either secured to the wall of the ship or it can be shoved into the rift inflated and taken out whenever it is desired to use the same; that is to say when the gun is ready for firing. After the air is let out of the hose secured to the shield or the ships side, the gun shield can then bev turned around without hindrance.

In the drawing the object of the inven tion is represented in two embodiments.

Figure 1 shows the gun shield to which- F ig 5 is a view seen from the top of Fig. 4, with partial section on line C-D of Fig. 4 at the height of the porthole. Fig. 6 is a sectional elevation taken on the line EF of Fig. 4, and Fig. 7 is a section on line G-I-I of Fig. 5.

Like numerals of reference indicate the same parts throughout the several figures in which;

1 indicates the gun shield, 52 the gun barrel and 3 the ships side.

As will be seen from the drawing the packing of the rift of the turret or casemate porthole is accomplished by the shoving in the rift of a deflated air hose 4 from the inside of the shi between the gun shield l and the ships side 3. The hose protected by suitable means against injuries is so shoved in that its ends 5 and 6 overlap. The closing of the hose is accomplished by the simple cementing of the overlapping ends. After the hose has been shoved into the rift it is inflated by means of an air pump or by introducing compressed air by means of a suitable valve 7 so that the hose when inflated at 8 and 9 provides a perfectly tight packing.

As is shown in Fig. 3 the packing device consists of the actual air hose 10 covered by a rubber cover 11, or the hose may be provided during its manufacture with a solid envelop (Figs. 6 and 7). coating 11 a water tight canvas envelo 12 may be advantageously arranged, the ru her as well as the canvas covering can be formed in the shape of a hose, but in the embodiment shown in the drawing they are both represented as strips which are wound around the air hose and secured to the same by screw clamps or by other suitable means.

In the construction shown in Figs. 4 to 7, the packing device consist-s of two single parts, one of which packs the lower part of the rift of the turret or casemate porthole, and the other packs the upper and side parts of the rift.

As will appear from Figs. 5, 6 and 7 a fixed canvas strip 13 is secured to the lower end of the gun shield 1 towhich strip the canvas cover 12 is sewed or connected in any other suitable manner. In this covering 12 the air hose 10 provided with a solid envelop is lodged. The covering 12 and the hose 10 extend to the ships side, and after the inflation the ends 14 of the packing, the

Over the rubber part secured to the ships side, as well as the loose shoved-in hose, pack at the ships side at a.

Having thus described the several parts of my invention what I claim as new and desire to secure by LettersPatent of the United States is The combination of a gun-shield for closing the portholes in gun turrets or casemates in warships with an inflatable packing tube, said inflatable packing tube being inserted in the rift between the porthole or caseniate wall and the gun shield while the said inflatable packing tube is in a deflated condition, said inflatable packiri tube eX- tending all around said gun-shiel and overlapping at its ends; the said inflatable packing tube being caused by inflation to closely follow the form and contour of the parts in such manner as to completely seal the rift in a watertight manner.

In witness whereof I have hereunto signed my name this 16th day of February 1909, in the presence of two subscribing witnesses.

MAX NOACK.
